animation track with two stripes and second stripe strart where first stripe ends?
Finally, I to solved my problem:
I create Stripe with cube moving from 0,0,0 to 0,1,0. I create first Track with added this Stripe and second Track with this Stripe. I set Blending = Combine in Second Track. So the second Stripe begins when the first Stripe ends. At the end of the Tracks is cube on the position 0,2,0.
